Bidens plant named 'SUNBIDEVB 1'

Abstract

A new and distinct cultivar of Bidens plant named ‘Sunbidevb 1’, characterized by its upright to outwardly spreading and mounding plant habit; moderate vigorous growth habit; freely branching habit; freely flowering habit; year-round flowering habit; inflorescences with bright yellow-colored ray florets which become lighter yellow towards the apex under high temperatures conditions; and good garden performance.

Description

Botanical designation: Bidens ferulifolia.

Cultivar denomination: ‘SUNBIDEVB 1’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Bidens plant, botanically known as Bidens ferulifolia and hereinafter referred to by the name ‘Sunbidevb 1’.

The new Bidens plant is a product of a planned breeding program conducted by the Inventor in Fukaya, Saitama, Japan. The objective of the breeding program is to create new compact and mounding Bidens plants with year-round flowering habit and numerous attractive inflorescences.

The new Bidens plant originated from a cross-pollination made by the Inventor in Fukaya, Saitama, Japan during the spring of 2010 of two unnamed proprietary selections of Bidens ferulifolia, not patented. The new Bidens plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Fukaya, Saitama, Japan during the autumn of 2010.

Asexual reproduction of the new Bidens plant by vegetative cuttings in a controlled environment in Fukaya, Saitama, Japan since the spring of 2011 has shown that the unique features of this new Bidens plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Bidens have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Sunbidevb 1’. These characteristics in combination distinguish ‘Sunbidevb 1’ as a new and distinct Bidens plant:

• • 1. Upright to outwardly spreading and mounding plant habit.
  • 2. Moderate vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Freely flowering habit.
  • 5. Year-round flowering habit.
  • 6. Inflorescences with bright yellow-colored ray florets which become lighter yellow towards the apex under high temperatures conditions.
  • 7. Good garden performance.

Plants of the new Bidens differ primarily from plants of the female parent selection in the following characteristics:

• • 1. Leaves of plants of the new Bidens have serrated margins whereas leaves of plants of the female parent selection have entire margins.
  • 2. Plants of the new Bidens are freely flowering year-round whereas plants of the female parent selection are not freely flowering under low temperature conditions.

Plants of the new Bidens differ primarily from plants of the male parent selection in the following characteristics:

• • 1. Leaves of plants of the new Bidens have serrated margins whereas leaves of plants of the male parent selection have entire margins.
  • 2. Plants of the new Bidens are freely flowering year-round whereas plants of the male parent selection are not freely flowering under high temperature and long photoperiods/short nyctoperiod conditions.

Plants of the new Bidens can be compared to plants of Bidens ferulifolia ‘Danyel9’, disclosed in U.S. Plant Pat. No. 20,968. In side-by-side comparisons, plants of the new Bidens differ primarily from plants of ‘Danyel9’ in the following characteristics:

• • 1. Plants of the new Bidens are broader than and not as upright as plants of ‘Danyel9’.
  • 2. Plants of the new Bidens have smaller leaves than plants of ‘Danyel9’.
  • 3 Leaves of plants of the new Bidens have serrated margins whereas leaves of plants of ‘Danyel9’ have entire margins.
  • 4. Plants of the new Bidens flower earlier than plants of ‘Danyel9’,
  • 5. Plants of the new Bidens are freely flowering year-round whereas plants of ‘Danyel9’ are not freely flowering during the summer.
  • 6. Plants of the new Bidens have smaller inflorescences than plants of ‘Danyel9’.
  • 7 Plants of the new Bidens do not produce seeds whereas plants of ‘Danyel9’ produce seeds.
